I wanted to add some new outlets in the basement / garage as the only existing outlets shared a 15 amp breaker with the lights and it would trip with any power tools I used.
I decided to install a subpanel and run dedicated outlets equidistant around the basement.
I began by running 6/3 with ground NM-B straight down from the main panel into the unfinished basement / garage (it's above ground)
Next I added a 60A 2 pole breaker in the main panel.
Subpanel & Breakers
Next I added a square d panel in the basement with 20A breakers and a ground bus.
Don't forget to make sure your neutral bus is isolated from ground!
12-3 romex nm-b w/g to outlets
Next I ran 12-3 romex nm-b w/g around the basement and down 1/2" MIT conduit into 4" square boxes and installed 20A GFCI outlets.
